No one may threaten or commit violence ('aggress') against another man's person or property. Violence may be employed only against the man who commits such violence; that is, only defensively against the aggressive violence of another. In short, no violence may be employed against a non-aggressor. Here is the fundamental rule from which can be deduced the entire corpus of libertarian theory.
Murray RothbardWe must, therefore, emphasize that 'we' are not the government; the government is not 'us.' The government does not in any accurate sense 'represent' the majority of the people. But, even if it did, even if 70 percent of the people decided to murder the remaining 30 percent, this would still be murder and would not be voluntary suicide on the part of the slaughtered minority. No organicist metaphor, no irrelevant bromide that 'we are all part of one another,' must be permitted to obscure this basic fact.
Murray RothbardThe natural tendency of government, once in charge of money, is to inflate and to destroy the value of the currency.
Murray RothbardInstead of a bumbling and inefficient tool of society, the radical [libertarian] sees the State itself, in its very nature, as coercive, exploitative, parasitic, and hence profoundly antisocial. The State is, and always has been, the great single enemy of the human race, its liberty, happiness, and progress.
Murray RothbardGovernmental subsidy systems promote inefficiency in production and efficiency in coercion and subservience, while penalizing efficiency in production and inefficiency in predation.
